The first type: the original stone has been lost for a long time. The original extension has a great influence on calligraphy and is representative. Although there are various differences in the quality of various rubbings in the future, they still feel precious and can be called "rare books". For example, the tablet of Huashan Temple in Xiyue, and the old stone is in Xiyue Temple in Huayin, Shaanxi. There are 22 lines of official script, each with 38 words. Jiajing 1555 in Ming Dynasty was destroyed by the earthquake, and it was engraved with Guo Xiangcha's book and Yingchuan Handan Gong. Now there is a copy of Changyuan, and the most important one is the copy of the Northern Song Dynasty collected by King Hebei. The handwriting is only cross-damaged, which was bought by Nakamura, Japan. Second, Huayin edition (Guanzhong edition) is a non-rubbinged edition collected by Dongzhi Library of the original county in the historical and geographical years. Later, it was collected by Hong, indicating that nearly 100 words of rubbings were incomplete, and it is now in the Palace Museum in Beijing. Third, the four Ming editions and rubbings collected by Fengxi (Daosheng) in Zhejiang Province were later collected by Ningbo Tianyi Pavilion Fan, but the number of residual characters increased. Duan Fang collected and recorded in the Qing Dynasty, and now it is also in the Palace Museum. Li Wentian also has half of Song Tuo's book, because this half of the book has been kept in private, and it was not known to the world until the Ma Rilu brothers hid it in Linglong Mountain Pavilion in the early Qing Dynasty, and there were more defects than white river cracks. Now it is kept by Mr. Ouyang of the Chinese University of Hong Kong, and Mr. Ouyang has a postscript. From the comparison of these four rare books, Changyuan is the best.
The second type: the initial extension of the original stone, due to factors such as extension and material, as well as storage factors, the quality of the original stone extension is different. For example, there are not many rubbings of original cinnabar (golden red) carved by the emperor, but they are found in Beijing and Taiwan Province Province. Later ink rubbings were not as good as Zhu rubbings and the first rubbings. One is the craft, the other is the long time interval and the material problem, so the vermilion version has become a rare version in seal cutting. Another example is the "Tomb of Brick Pagoda of Wangfu" unearthed in whipple Valley, Zhong Nanshan, Shaanxi Province during the Wanli period of the Ming Dynasty. In the south of Chang 'an County, the initial extension has been broken into three pieces, then five pieces, and then split into seven pieces. Later, the first piece was lost due to handling, and it all hit the extension of the vertebral body, so the initial extension was extremely rare. Liaoning Museum has the best rare books unearthed in Ming Dynasty.
The third type: the original stone still exists, but it is damaged too much, while the old rubbings are complete. This situation is because the original stone is stored in the wild, or the stone is poor in quality or struck by lightning, so the original rubbings are also very rare, which can be called "rare books". For example, the old stone in the epitaph of Sui Jishi was unearthed in Xianning, Shaanxi Province in the twentieth year of Jiaqing (18 15), and the stone of Lu Yaoqing in Wujin was moved to Jiangzuo. In the tenth year of Xianfeng (1860), the word 170 was divided into two sections, and the original stone was the first. After the war, the residual stone was recovered by Lu Yanfu, which was incomparable with the original stone rubbings. However, due to its superb calligraphy skills, the original rubbings can be called treasures, which is described in the Tomb Records of the Han, Wei, Southern and Northern Dynasties (edited by Zhao Wanli). The original stone is hidden in the Forbidden City in Beijing.
The fourth type: the original stone flows abroad, and few rubbings are preserved in China. These foreign inscriptions are of high artistic quality, with few rubbings, and some are even restored. These inscriptions are generally found in the late Qing Dynasty and the Republic of China, and some of them were sold or looted because of political corruption in the Han Dynasty. For example, in 19 19, a gold monument was unearthed in Luoyang, Henan Province. The tablet is small, with the first 19 lines and the last 6 lines 19 characters, all of which are official scripts. Because the political situation was turbulent at that time, no one took care of it and was bought by the Japanese who heard the news. There are not many rubbings in China, and most of them are reprinted. Compared with the original rubbings, the factory flowers in the left corner show traces of knives and axes. However, Zhang Langbei has not only the artistic value of calligraphy, but also the value of literature and history, so the monument is small but also a treasure.
